FASTENING nnvron.

Application filed January My invention is an improved fastening devicewhich is particularly well adapted for use in holding a fire place stopor front cover in place, and it consists in the combinations,constructions and arrangements hereindescribed and claimed.

An object of the invention is the provision of a fastening device of thecharacter described which can be adjusted at will to 'vary W theefiective length thereof within a considerable range.

A further object of the invention is the provision of a fastening deviceof the character described which includes means for i5 holding thefastening device taut or under tension and for preventing displacementof the parts of the fastening device when the fasteningdevice has beenapplied.

Other objects and advantages of the i11 vention will be apparent fromthe following description, considered in conjunction with theaccompanying drawings, in which- Figure 1 is a perspective view. showinga fire place stop or cover held in place by fas tening means embodyingthe invention,

Figure 2 is a relatively enlarged fragmenr tary plan sectional view,showing one of the units of the fastening means exhibited in Figure 1,and portions of the fireplace wall and the fireplace stop or frontcover,r.espectively,

Figure 3 is a perspective view showing a fastening unit embodying theinvention and including a modified form of springtensioning member. p

In Figure 1, the numeral 1 designates a stop or front cover for a'cavityor fireplace (partially shown at 2) in a wall 3. A pair of fasteningunits embodying the invention in the form now preferred by me are shownin Figure 1 as holding the fireplace stop or cover in place, eachfireplace unit being indicated at U. The specific fireplace stop orcover is disclosed and claimed in my prior 5 application forLettersPatent of theUnited' States, Serial #523,309, filed April 15,1925, 'and will not be" described in detail nor claimed herein; i

As shown to advantage in Figure 2, each of the fastening units Uincludes an elongated supporting member which may comprise two.elongated bar-like sections indicated at d and 5, respectively. A Thesection 5 is formed witha longitudinally extending 2, 1926. Serial no.78,997.

slot 6; The section 1 is formed with a transverse opening 7 adjacent toone end thereof and a suitable fastening device, such as abolt 8extends'through the opening 7 and through theslot 6 and is threadedlyengaged with a nut 9 which can be tightened against the section 5 tohold the sections 4 and 5 against relative longitudinal movements,whereby the effective length of the sections 1 and 5 combined can bevaried within a considerablerange, The section 4: is provided adjacentto its free end with a longitudinally extending slot 10 which isenlarged at its inner end or in other words at the end thereof nearestto the section 5,'as indicated at 11.

A right angular cured rigidly to the convex faceof a substantially semielliptical spring tensioning bar 13 intermediate the length of thespring tensioning' bar. The .second'arni of the'right angular bracket isindicated at 14' and is disposed flatwise against the adjacent or outerend portion of the section 5 of the fastening unit, being connected withthe section 5 by a horizontal bolt 16 which extends through alignedopenings in the outer end portion of the section 5and the bracket arm 14and is threadedly engaged by a nut 17 It may be noted at this point thatthe bracket arm 12 can be secured to the spring bar 18 in any suitableknown mannenas by welding. The spring bar 13 is provided with a threadedopening 18 which is formed through the spring bar intermediate thelengthof the latter and in register with an opening 19 in the bracket arm 12.The shank of the bolt 20 may be extended through the aligned openings 18and 19 and may threadedly engage with the wall of the opening 18. Thisbolt is of sufficient length to extend beyond the plane of the contactportions at the ends of the spring bar 13 when the head of the: bolt isin contact with the bracket arm 12. 7

bracket has anarm 12 se- The contact portions at the ends of thespring-bar areindicated at ,21 and are reversely curved end portions ofthe spring bar 13 which thus present convexly curved C ntact faces tothe inner wall of the fire- P1528 cover 1 when the bolt shank isprojected through'an opening 22 in the fire place cover 1, as shown inFigure 2. The extending end portion of the shank of the bolt 20 isadapted to be threadedly engaged by the internally screw threaded sleeveporthereofmay be readily understood.

enlarged end portionll at one end or tion 23 of an adjusting memberwhich may have av knob or like outer end portion or handle indicated at2 1.

A stud 25 is adapted to be driven into the fireplace wall to extendwithin the fireplace cross section than the enlarged end portion 111atthe inner end of the: slot; 10.

From the foregoing description of the various'partsofthe device, theoperation The effective length of the sections '4 and 5 of a fast ningunit embodying the invention is adjusted as desired and the fasteningunit then is manipulated to cause the head 26 ofthe ancho 'ing stud topass through the the slot 'lO. Thefastening unit thenvis moved outwardlyuntil the shank of the anchoring stud has slidin the slot IOagainst theopposite end of the sl'ot lO. The bolt then is projectedthrough-the'opening 22 in the fireplace cover 1 and the adjusting member282t is tightened on the bolt- 20 against the action of the springtensioning member 13'until themarginal edge portions of the fireplacecover have been drawn tightly against the-front-face of the fireplacewall and thespring tensioning member l3-has been elongated from theposition-shownby the full lines in Figure Q to the position indicated bythe dot-ted lilies in thesame figure. 'The spring member .13 thereforeserves not only to hold the fastening unit under tension and taut butalso-tends-toprevent'accidental displacement of the adusting member-2324"from a desirable position on the bolt 20.

It will be understood that whentwo of the fastening units v U'areemployed to hold the fire-place coverjin place as shown in Figure 1,said fireplace cover has two of the openings 22 which respectivelyare-located adjacent to opposite sideedgesofthe fireplace cover. Also,two of the anchoring studs 2526 are provided, the "respective anchoringstuds extending into the fireplace or cavity from opposite side walls.ofthe latter.

The modificationshownin Figure 3is identical with the fastening unithere1nbefore described and 111 addition-includes a second springtensioning member, indicated 7 at 33. The spring member 33a-lso issemielliptical in 7 form and is provided intermediate its ends with anopening 3 1 through which the shank of the bolt 20 extends. Thespringmember 33 is arranged at right angles to the spring member 13 and.has the end portions thereofcu'rved reversely as indicated at 35 so asto present convexly curved contact facesto the inner wall of thefirethat the effective length -meansconnecting the said registeringopenings beyond place cover,

- that the posed at a lower level than the openings lathe-fireplacecover so that the tighten ng of the fastening devices will draw the fireplace cover firmly down against the hearth as well as against the frontwall of the .fireplace structure. If desired, 5 may use a softwire ofsufiicient strength to connect the stud 2526 withthe member 14 in lieuthe'bars 4 and 5.
